Sinva Forest

Sinva Forest is one of the pristine and little-touched natural areas in Chalus County, Mazandaran Province. It lies along the Chalus–Marzanabad road, around the village of Sinva. Because it sits at high elevation and close to the Hesel road, the forest offers a remarkable variety of landscapes and is regarded as one of the high points of central Chalus. Its particular geographic setting has created a combination of dense forest, seasonal mist and mountain scenery.

One of the most important features of Sinva Forest is its rare natural attractions, such as Hesel Marsh and Vorban Marsh, which lie deep within the dense forest cover and create a mysterious, strikingly beautiful atmosphere. These marshes are set among thick trees and leaf-covered trails, and in autumn and spring in particular they take on a unique look as they reflect the colors of nature. Sinva Waterfall (Shorshor), about 25 meters high, is another major attraction of the area. It pours down over rocks covered with moss and wild plants, creating a spectacular view.

Sinva Forest can be reached via the Chalus road and then the side road to Sinva village, and some sections of the route require walking through the forest. The best time to visit is spring and autumn, when the forest is at its most beautiful and the mist and natural colors give it a special charm. When visiting, it is very important to practice responsible nature tourism, avoid entering the sensitive parts of the marshes, and keep the surroundings quiet to prevent disturbing the natural ecosystem.
